DETAILED DESCRIPTION OF THE INVENTION

Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

In various exemplary embodiments, the technology described herein provides an air deflector assembly to redirect the air flow emitted from a slot type air diffuser.

Referring now to the Figures, an air deflector assembly 10 having an arc deflector 12 for a slot air diffuser 14 is shown. The arc deflector 12 is configured for placement suspended from a slot air diffuser 14 having a slot opening 18 for emission of a central air flow 16 from a central heating and cooling system. The air emitted from the slot air diffuser 14 is dispersed and directed by the arc deflector 12. The arc deflector 12 can be used in building areas where occupants served by a slot air diffuser 14 are uncomfortable due to inadequate air dispersal from the slot air diffuser 14.

In at least one embodiment, the arc deflector 12 is constructed of a paint grade sheet metal with a powdered coated finish. In at least one alternative embodiment, the arc deflector 12 is constructed of an extruded acrylic or plastic. The arc deflector 12 can be manufactured in a variety of colors dependent on arc deflector placement location in a home or building and user choice preferences.

The arc deflector 12 can be a curvilinear panel configured to facilitate the dispersion and direction of air flow emitted from the slot air diffuser 14. The arc deflector can be utilized such that a concave side of the arc deflector 12 faces the slot opening 18 of the slot air diffuser 14. Such utilization catches the central air stream emitted at the slot air diffuser 14 and directs it across the ceiling, or like area dependent on location of the slot air diffuser 14.

The air deflector assembly 10 includes an attachment means by which the arc deflector is attached to a slot air diffuser 14. By way of example, the arc deflector 12 can be supported by hanging on an inside lip of the slot opening 18 of the slot air diffuser 14. Various embodiments of the air deflector assembly 10 include varied means of attachment. By way of example, the arc deflector 12 can attached to a slot air diffuser 12 mounted in a ceiling 22.

In at least one embodiment, the arc deflector device includes at least one mounting bracket disposed upon the arc deflector 12 and by which the arc deflector 12 is suspended from the slot opening 18 of the slot air diffuser 14. The at least one mounting bracket can be integrally formed with the arc deflector, such as by welding in a metal embodiment and by molding and/or extrusion when in a plastic embodiment.

By way of example, two angle brackets 20 can be utilized for the attachment means. The angle brackets 20 can be L-shaped, T-shaped, or the like, at the top of the bracket 20, such that the arc deflector 12 is placed in the slot opening 18 and remains there securely and safely. The angle brackets 20 can be welded to, or otherwise integrally formed with, the arc deflector. The angle brackets 20 can include holes to provide additional means of attachment, such as for example, connectivity to a loose bracket 40 to form a T-shape when to L-shaped angle brackets are utilized.

In an alternative embodiment, the means of attaching the arc deflector 12 to the slot air diffuser 14 includes a dovetail bracket 24. By way of example, and as best depicted in FIG. 8, the dovetail bracket 24 can include a female dovetail 32. A male dovetail 34 is utilized on the concave side of the arc deflector 12. The male dovetail 34 can run the length of the arc deflector 12. Arm 38 is configured with clips 36, or the like, that can be integrally formed, to secure the dovetail bracket to the slot opening 18 of the slot air diffuser 14. The gap in the arm 36 located between clips 36 allows the arm 36 to be squeezed from both sides to insert the dovetail bracket 24 into the slot opening 18 of the slot air diffuser and provide a tension to hold the arc deflector 12 securely and safely in place. The male dovetail 34 on the arc deflector 12 can be slid into the female dovetail of the dovetail bracket 24.

In yet another alternative embodiment, the means of attaching the arc deflector 12 to the slot air diffuser 14 includes a pair of end caps 28 disposed upon the arc deflector 12 at each end to prevent emitted air from exiting out the ends of the air deflector 12. By way of example, and as best depicted in FIG. 7, a threaded rod 30 can be threaded vertically through each end cap 28 and secured with lock nuts, mandrel, and the like. Attached to the threaded rod 30, is an expander 26, such as an expander fitting, which can be rotated to expand outwardly and secure the arc deflector 12 to the slot air diffuser 14. A locking nut threaded behind the expander 26 causes the angles to spread apart and hold the angles in place. The threaded rod 30 can be part of the arc deflector in the extruded bracket embodiment or welded on the metal embodiment at a ninety-degree angle from the apex of the arc.

A method for deflecting air emitted from a slot air diffuser 14 is disclosed. The method includes utilizing an arc deflector 12 configured for placement suspended from a slot air diffuser 14 having a slot opening 18 for emission of air from a central heating and cooling system. The emitted air is dispersed and directed by the arc deflector 12. The method also includes mounting the arc deflector 12 to the slot opening 18 of the slot air diffuser 14 by an attachment means and dispersing and directing the emitted air as it exits from the slot air diffuser 14.

The method can also include mounting the arc deflector 12 to the slot opening 18 of the slot air diffuser 14 by at least one mounting bracket, such as 20, disposed upon the arc deflector 12 and by which the arc deflector 12 is suspended from the slot opening 18 of the slot air diffuser 14.

The method can also include mounting the arc deflector 12 to the slot opening 18 of the slot air diffuser 14 by utilizing a dovetail disposed upon the arc deflector 12 and by utilizing a dovetail bracket 24 configured to mount in the slot opening 18 of the slot air diffuser 14 and configured to join with the arc deflector 12 dovetail.

The method can also include mounting the arc deflector 12 to the slot opening 18 of the slot air diffuser 14 by utilizing a pair of end caps 28. An end cap 28 is located upon the arc deflector 12 at each end to prevent emitted air from exiting out the ends of the arc deflector 12. The method also includes utilizing an expander 26 disposed upon each of the pair of end caps 28. The expander is mounted upon a threaded rod 30 to secure each end cap 28 to the air deflector 12 and by which the air deflector 12 is suspended from the slot opening 18 of the slot air diffuser 14.
